Cellerator Wants To Be Your Automated Desktop Biotech Lab

August 17, 2020 by Mike Szczys 8 Comments

Cellerator really had us at “make designer beers”, but of course this multi-purpose biotech lab has a lot more to offer. It seeks to lower the cost and complexity barriers for automating useful scientific equipment, and wants to pave the way for more innovation in material science based.

The approach taken by Cellerator is to take existing lab tools and automate common research tasks using components familiar to anyone who’s used a 3D printer. A gantry system with end effectors designed for different tools like pipettes automate the processing of samples. A camera (with or without microscope) can be used for feedback via computer vision, or simply by logging snapshots.

A number of screenshots from the software show the depth of the plans for the system. They include widgets for telling the system where various fixtures such as the hot plate, centrifuge, and bioreactor are located. Sub menus for each tool set parameters for their operation, with a scheduling and instruction system for customizing each experiment as well as recording all of the data along the way.

Cyborg, Or Leafy Sensor Array?

Some plants react quickly enough for our senses to notice, such as a Venus flytrap or mimosa pudica. Most of the time, we need time-lapse photography at a minimum to notice while more exotic sensors can measure things like microscopic pores opening and closing. As with any sensor reading, those measurements can be turned into action through a little trick we call automation. [Harpreet Sareen] and [Pattie Maes] at MIT brought these two ideas together in a way which we haven’t seen before where a plant has taken the driver’s seat in a project called Elowan. Details are sparse but the concept is easy enough to grasp.

We are not sure if this qualifies as a full-fledged cyborg or if this is a case of a robot using biological sensors. Maybe it all depends on which angle you present this mixture of plant and machine. Perhaps it is truly is the symbiotic relationship that the project claims it to be. The robot would not receive any instructions without the plant and the plant would receive sub-optimal light without the robot. What other ways could plants be integrated into robotics to make it a bona fide cyborg?

Researchers Seek To Create The Digital Smell Interface

November 15, 2018 by Drew Littrell 18 Comments

We hear digital audio, we see digital video, and we feel digital haptic feedback. However, we don’t have an analog for the sense of smell. [Kasun] and his team of researchers from the Imagineering Institute in Malaysia are in the midst of changing that reality. Their project aims to transmit fragrances via electronic stimulation. Though it’s really more of a step toward creating a multi-sensory internet.

The team’s “electric smell machine” consists of a variable power supply connected to silver electrodes wrapped around an endoscopic camera. The camera is necessary to ensure contact with the user’s olfactory bulb as electric current pulses through the electrodes. The current values vary based upon the scent being replicated and are in the 0.2mA neighborhood. Early trials of the machine have revealed that around one-quarter of test subjects are able to identify the smells being replicated. They reported smells being fruity, sweet, and woody though all had a chemical-like odor attached.

The concept of “smell-o-vision” is not a new one, as it has been around longer than motion pictures with sound. Previous attempts at accompanying film and television with scent have been a result of chemical reactions. Devices from these types of experiments typically involved cartridges that would need to be replaced when the chemical substances were depleted. [Kasun]’s team approach is to avoid the chemical approach in favor of directly stimulating the olfactory receptors. Those interested in the gritty details can read the research paper on digitizing smell.

[Kasun] and his team uploaded a video on the project that you can view below. It’s all a work in progress at this point, but sign me up for a trial when they pinpoint the true essence of new car smell.

Artificial Skin Lets Robots Feel

August 2, 2012 by Richard Steele 32 Comments

BioTac Artificial Skin Technology is sure to be a storm with Robotics Designers. Giving them the opportunity to add a third sense to there robotic marvels. Now they can have the sense of touch to go along with existing technologies of sight and of sound. Thanks to the technology coming out of the University of Southern California making this possible.

They have chosen to call their sensor BioTac, which is a new type of tactile sensor designed to mimic the human fingertip with its soft flexible skin. The sensor makes it possible to identify different types of texture by analyzing the vibrations produced as the sensor brushes over materials. This sensor is also capable of measuring pressure applied and ambient temperature around the finger tip, expect to see this technology in next gen prosthetics. Let us know your thoughts on it.
